Which sequence of transformations maps triangle ABC to its image triangle A''B''C'' (the blue triangle)?

• A reflection over the x-axis, then a rotation.

• A reflection over the y-axis, then a rotation.

• A 90° rotation, then a reflection over the x-axis.

• A 180° rotation, then a reflection over the y-axis

Which statement best supports the conclusion that the figures are congruent?

• Each vertex of quadrilateral M was translated 10 units right and 1 unit down to produce quadrilateral M'.

• Quadrilateral M was reflected across the x-axis to produce quadrilateral M'.

• Each vertex of quadrilateral M was translated 2 units right and 8 units down to produce quadrilateral M'.

• Quadrilateral M was rotated 180 degrees about the origin to produce quadrilateral M'.

What is the new ordered pair of points (5,1) if it is translated 6 units up and 3 units to the left?

• (11,1)

• (11,-2)

• (2,7)

• (7,2)

Shaun draws parallelogram PQRS on the coordinate plane. He will translate the parallelogram 3 units up and 3 units to the right to create parallelogram P'Q'R'S'. Which statement about parallelogram P'Q'R'S' is correct?

• Parallelogram P'Q'R'S' has 3 times the area of parallelogram PQRS.

• Parallelogram P'Q'R'S' has 6 times the area of parallelogram PQRS.

• Parallelogram P'Q'R'S' has the same area as parallelogram PQRS.

Square PQRS is rotated counterclockwise 90 degrees about the origin. Which side in the new square corresponds to SR?

• AB

• BC

• CD

• AD

Angelica transforms triangle ABC to form triangle A'B'C'. The resulting triangle is congruent to the original. Which transformations result to congruent triangles?

• reflection only

• rotation only

• translation and rotation only

• translation, rotation, and reflection

If a point A(-2,5) undergoes a 90-degree clockwise rotation and is then reflected about the x-axis, what are the coordinates of A'?

The graph shows the squares ABCD and A'B'C'D'. Which of these statements is true?

• The squares are congruent because a 180 degrees clockwise rotation of ABCD about the origin gives A'B'C'D'.

• The squares are congruent because a 90 degrees clockwise rotation of ABCD about the origin gives A'B'C'D'.

• The squares are congruent because a 270 degrees clockwise rotation of ABCD about the origin gives A'B'C'D'.

• The squares are congruent because a 90 degrees counter-clockwise rotation of ABCD about the origin gives A'B'C'D'.
